Newbie question on amp input switch for passive or active

    Just picked up my first active bass. I get the whole "the input switch on the amp reduces the signal 10db" to account for the stronger output of the active electronics. But what if the active bass is not driving the input signal any harder than my passive bass (with Duncan Antiquity II pickups)? If I leave my amp input switch in the passive mode, my amp is not clipping and the output of at the speakers is the same for both basses. Am I hurting anything?

    Nope, no harm done. In fact, some people recommend using the "passive" input at all times unless your bass signal really does clip the preamp. A side note: not all amps are designed the same. Some have a different amount of dB pad, and some adjust the input impedance as well, to accommodate the different output impedance of an active bass. You'll just have to rely on the owner's manual to know how your amp is designed.
